All releases of OS/VS2 were available to no charge because the software cost was bundled with the hardware cost. OS/VS2 Release 3.8 was the last free release of MVS. In the late seventies and early eighties IBM announced:
So OS/VS1 and SVS in principle had the same disadvantages as MFT and MVT, but the impacts are less severe because jobs and operators could request much larger partitions with a 2 KiB granularity (for OS/VS1) or regions with a 4 KiB granularity (for SVS), and the requests came out of a 16MiB address space even if physical storage was smaller.
